Definitions
- the present invention relates to an apparatus designed to be mounted on an agricultural sprayer with the purpose of decreasing the drift and improving the deposition, penetration and uniformity of distribution when applying liquids such as pesticides and liquid plant nutrients used in agriculture, horticulture and forestry.
- Application of pesticides may be executed with areal spraying with agricultu- ral sprayer, band spraying or contact application.
- Areal spraying implies that the whole field is prepared/sprayed while band spraying means that only one band including the planting row or the space between the planting rows is sprayed.
- Contact application means that the pesticide is transferred by direct contact. This type of control occurs only to a limited extent and only in specific control situations.
- Conventional methods for areal spraying comprise agricultural sprayers equipped with hydraulic sprayers uniformly spaced at a distance of 50 cm along the boom. When spraying, only a fraction of the sprayed liquid reaches the noxious object. Portions of the spray liquid will drift with the wind or evaporate, and some portions will land on the ground or on parts of the plants where the liquid has no effect. Different estimations of the fraction of the sprayed liquid which actually has effect, i.e. reaches the spray target, varies between 0,1 to 30%.
- High boom level High boom level, 50 cm above the ground, is required to achieve a uniform liquid distribution. This increases the risk for drift.
- a cause of increased drift is, among other things, that the droplets are exposed to the wind during a long time period on their way from the nozzle to the spray target. This, in combination with the fact that the wind velocity increases exponentially with increasing distance from ground, makes the boom level an important contributor to the drift.
- Boom movements is one of the most important causes for a non-uniform liquid distribution. Both horisontal and vertical boom movements may cause substantial dose variations over the field. The non-uniform liquid distribution results in poor treatment effect, which must be compensated by an increased dose. In addition, there is a risk of damage on the crop in places which receive the highest doses. The vertical boom movements involve also often damage on the nozzles when these are forced into contact with the ground and crop.
- Drift The drift is a problem of great concern which is affected by weather conditions, spray quality and exposure of the droplets to weather influence. At given weather conditions, the only possible measure to reduce the drift with conventional methods is to choose a coarser spray quality. Conventional methods normally use medium or coarse spray quality (big droplets). Coarser spray quality involves lower degree of coverage and therefore lower pesticide control effect which must be compensated with higher dose.
- liquid quantities in the order of 200 1/ha (litres per hectare) is often recommended in application onto low crop stands and 300-400 1/ha onto high density and high crop stands.
- These relatively large liquid quantities decrease the efficiency of control because of the increased number of refillments required, which increases the costs and decreases the spray time. It is not rare that refillments, including transports, occupy one third of the total treatment time.
- the weather is a very limiting factor for chemical control and the number of opportunities to spray are few. Consequently, it is of great importance that the spray opportunities are efficiently utilized.
- the possibility to conduct control at optimal time also maximizes the biological effect and facilitates dose reduction.
- Band spraying means that a band, including the planting row or the space between planting rows, is sprayed.
- the method is used for row growing crops such as sugar-beets, strawberrys and outdoor cultivated vegetables.
- Band spraying may be performed with a modified agricultural sprayer or a separate suitably equipped machine.
- the nozzles are often mounted on runners, such as described in US Patent no. 2580145 and German patent no 1482350. In some cases also tunnels are used to protect both the spray shower from external influence and the portions of the ground/crop not to be sprayed.
- Air assistance may be classifed according to two principles, internal or external air assistance.
- Internal air assistance means that air is added (by means of a compressor or a fan) inside the nozzle so that the air, together with the liquid, contributes to the droplet formation itself.
- the principle of internal air assistance makes it, under some circumstances, possible to keep the size of the droplets constant within a certain range, independent of the water flow.
- the required amount of liquid and size of droplets are loaded into a spray computer which controls air and liquid pressure.
- These systems use conventional deflector nozzles and the recommended boom level is 50 cm or higher.
- nozzles are used where the air flow passes a wing, over which the liquid is led, and forms a film of liquid. The droplets are formed when the liquid is ripped off the edge of the wing by the air jet.
- the nozzles are spaced with a distance of 16 cm and the recommended boom level is higher than that for conventional methods.
- External air assistance means that the air is added (normally by a fan) outside the opening of the nozzle.
- the formation of droplets is made with conventional nozzles, and the purpose of the air addition is to increase the speed of the droplets towards the spray target.
- the velocity of the droplets is increased by direct influence of the air jet, or indirectly as the air jet creates a downwardly directed injector effect towards the spray target.
- the recommended boom level is the same as, or higher than that, for conventional methods.
- Another principle includes enclosing of the spray fan against the ground or crop in order to prevent the wind to affect the spray fan.
- crop openers available which opened up high crop stands and facilitated lowering of the boom.
- the constructions of the crop openers resulted in strong forces upon the boom construction which caused the booms to break.
- the crop openers therefore have disappeared from the market. From the drift point of view it is possible to achieve a positive effect with some applications of internal and external air assistance.
- the result depends to a great extent on the particular settings used, and, in some cases, settings decreasing the drift may result in a risk for poor biological effect. Incorrect settings of air quantities and size of droplets may even result in increased drift.
- External air assistance together with enclosed spray fan and crop opener, may increase the deposition into the crop substantially compared to conventional methods, but often at the expense of increased deposition onto the ground.
- the current methods have not satisfactory and sufficiently solved the problems of boom movements, boom level, deposition and wind drift.
- the methods are considerably more expensive than traditional methods and only in exceptional cases is it possible to after-mount the systems on an existing sprayer.
- the systems require extensive knowledge and carefulness for correct adjustment and all systems, except the one with enclosed spray shower, have at least one more demand for adjustment compared to conventional methods. Some of the systems also require that the adjustments are changed during work depending on wind direction and wind-force.
- the general purpose of the present invention is to provide an apparatus for application of liquids, such as pesticides, which decreases the drift and improves the deposition onto the spray target and improves the spray uniformity, minimizing the consumption of liquids (a rochemicals), decreasing the pressure on the environment and reducing the costs in agriculture.
- the apparatus is to be after- mountable on a conventional agricultural sprayer without requiring further adjustments.
- liquids in the present application refers primarily to chemical and biological pesticides, such as micro-organisms, different types of plant nutrients and the like, but also all kinds of liquids which can be applied by means of an agricultural sprayer and the apparatus of the present invention. Short description of the invention
- the purposes of the invention are achieved by a movable mounting of the nozzles, not on the boom but on a movable, separate part according to the invention, which gives in when making contact with ground or crop.
- the nozzles will therefore be at approximately the same distance above the spray target even if the ground is uneven and/or the spray boom is moving vertically.
- the distance between the nozzles and the spray target can therefore be shortened which decreases the drift. Without this resilient feature, there is an evident risk that the distance between the nozzles and the spray target becomes too short with non-uniform liquid distribution and/or damage on the sprayer as a consequence.
- the apparatus will open up the stand, which also improves the penetration into stands with high density.
- the spring system also decreases the risk of horisontal boom movements to impair the deposition.
- the invention relates to, besides providing the apparatus described in detail below, the use of this apparatus and a method for producing the central, movable part, below referred to as (A).
- This part provides a simple construction since it is made in one piece, with low production cost and sufficiently low weight to be mountable on existing booms at used agricultural sprayers.
- Figure 1 is a functional diagram of the invention mounted on a spray boom wherein:
- (A) is the movable part (the resilient construction)
- F x and F y are forces acting on the invention in x and y-direction, respectively.
- (E) is the direction of motion of the sheet when the force/forces F x and/or F y is/are acting upon it.
- (G) is the space between the resilient constructions when these are mounted on the sheet (B) and the spray boom (D).
- Figure 2 is detailed view of a preferred embodiment of the movable part (A) before bending, wherein:
- I is a line where stiffening by bending is made
- III is a hole for mounting of spray body
- V is a hole for mounting of the movable part (A) at the spray boom (D) in Figure 1.
- Figure 3 is a detailed view of a preferred embodiment of the movable part
- the invention comprises a resilient construction on which the sprayers (C) and a sheet (B) are mounted.
- the distance between the lower part of the sheet and the sprayer is fixed, which results in a constant distance between the nozzle and the spray target as the sheet follows the ground or the crop.
- the sprayers are backwardly angled, and the distance between nozzle and spray target (called boom height in conventional methods) is normally only about 20 cm, but may vary between 5-35 cm.
- the contact of the sheet with the crop or the ground leads to reduced boom movements.
- the fixed low boom level and reduced boom movements result in a substantial reduction of the drift in comparison with conventional methods, as well as in improved uniformity of the distribution. Since the exposure of the spray fan to the influence of wind is small, fine spray quality can be used and therefore it is possible to reduce the amount of liquid without decreasing the degree of coverage.
- the applied amount of liquid can be reduced to half of the recommended amount of conventional methods, which leads to a more time efficient control which means that larger areas can be controlled at an optimum point of time.
- the sheet opens up the crop and sets the crop in motion which improves the deposition in the stand.
- All the mentioned advantages such as small drift, good spray uniformity, high degree of coverage, and deposition in the stand and control at an optimum point of time give the possibility to reduce the doses with preserved treatment effect. This reduces the costs and decreases the environmental influence. Further, the apparatus is simple to operate without any extra demands on adjustments compared to conventional methods.
- the unique feature according to the invention comprises its movable part (A) which gives the apparatus its particular and desired characteristics.
- the apparatus comprises the part (B), called sheet, which comes into contact with ground or crop, and nozzle and armature (C), where the purpose of the nozzle is to disintegrate the liquid to be applied on ground or crop.
- Sheet and nozzle are mounted on the movable part which in turn is mounted on the boom (D).
- the apparatus according to the invention has, among other things, the following functions which solve the problems described in the background of the invention.
- the nozzles are movably mounted on the movable part/parts (A) and give in when brought into contact with ground or crop.
- the nozzles will therefore keep approximately the same distance to the spray target even if the ground is uneven and/or the spray boom is moving vertically. This makes it possible to keep a short distance between the nozzle and the spray target which results in decreased drift. Without this construction, there would be an evident risk that the distance between the sprayer and the spray target would become too short with non-uniform liquid distribution and/or damage on the nozzle as a consequence.
- the apparatus will open up the stand and set the crop in motion which leads to improved deposition and penetration of high density stands.
- the contact of the apparatus with the crop also produces a horisontal damping force acting on the boom which decreases the horisontal boom movements and therefore improves the uniformity of the distribution.
- the apparatus according to the invention reduces the wind drift by 84% compared to conventional methods and has an excellent deposition into the crop by its unique construction, which facilitates the use of small amounts of liquid.
- the substantial reduction of the drift made possible by the invention, allows the desired use of fine spray quality, i.e. smaller and finer droplets than by conventional methods.
- the apparatus of the invention has an individual mounting of the nozzles, i.e. the nozzles are not mounted directly on the boom. This enables a desired low boom level with a fixed distance between nozzle and spray target without jeopardizing the uniformity of distribution and risking nozzle damage.
- the nozzles are angled so that a uniform liquid distribution is achieved despite low boom level.
- the nozzles one or more, are directed sidewards in order to provide a possibility to spray the spray target from the side during, for instance, band spraying of row growing crops.
- the invention By the creation of a force, pointing in the backward direction along the boom, when the apparatus surfs on the ground or the crop during application, the invention involves decreasing boom movements.
- the advantage of a low weight of this part is obtained, in addition to other already described advantages.
- This is a precondition of the apparatus to be mountable on some boom constructions. Since the desired ability to move and spring can be built-in in one piece, there is no need for welding or assembly work during the production of the movable part. This is very advantageous, both from a production and a user point of view, since no problems with increasing costs of production and weakenings of the material arise.
- a preferred and suitable material for production of the part (A) is stainless steel, but other materials, such as plastic, can be used.
- Stainless steel plate fulfil the demands of a light construction with high structural strength and good resistance against chemicals, which provides an easy to care and handle apparatus for application of e.g. agricultural chemicals. This prescription should not be seen as a limitation but all materials with the desired qualities are conceivable for production of the part (A).
- a preferred manufacturing procedure comprises the following steps:
- the movable part (A) (Fig. 1), preferably manufactured from stainless steel SS 2331-43 0,8 mm, is preferably cut out by laser or water cutter.
- the part (A) has, for example, a size of 600 x 67 mm.
- the part (A) is bent along the dashed lines (I) and (II) (Fig. 2).
- the distances (I) (Fig. 2) are bent about 80 degrees in order to stiffen the part (A).
- the distances (II) are to be bend so that angle (1) (Fig. 3) is 40 degrees, angle (2) is 35 degrees and angle (3) is 31 degrees.
- the sprayer body with nozzle are mounted in hole (III) (Fig. 2) so that the centre line through to the nozzle is parallell to the distance (5) (Fig. 3).
- the piece mounted/manufactured according to the steps above, is mounted on the existing boom (D) (Fig. 1) at the point (V) (Fig. 2).
- the sheet (B) (Fig. 1) which is made of wear resistant plastic, or other suitable material, and has a width of 250 mm, is mounted symmetrically along the distance (4) (Fig. 3).
- the sheet is divided into sections according to the divisions of the existing boom (D) (Fig. 1).
- the distance (G) (Fig. 1) between respective part (A) (Fig. 1) is between 250 and 500 mm, preferably 330 mm.
- Distribution of spray liquid in a stand of potato with different application methods is 200 1/ha.
- the values refer to normalized deposition.
- Leaf 1 corresponds to the uppermost level in the stand.
- the usage of the apparatus of the invention provides: decreased wind drift and thereby decreased risk for damage on adjacent vegetation and environment, coverage of almost twice the area by lower amount of liquid per hectare and thereby an improved utilization of the hours well suited for spraying, twice the covered area per filling giving half the number of fillings, giving reduced risks for driver and environment, full weed control effect achieved with a lower dose.
- leaf herbicides Reducing the doses of soil herbicides may result in decreased effects and shorter long-term effect, and can not be generally recommended solely based on the use of the apparatus of the present invention.
- leaf herbicides is the predominant type of chemicals used in agriculture and a reduction of the doses of these agents will have a large impact on the total amount of pesticides being used.
